Several meta-analyses have shown that there is a correlation between greater consumption of coffee and lower risk for T2DM. However, no long-term randomized controlled trials have established causality, or demonstrated that drinking coffee reduces the risk of developing diabetes.[11]

According to a recent analysis, individuals who increase their daily intake of coffee by around 1.5 cups have an 11% lower risk for T2DM, whereas those who decrease it by a median of 2 cups have a 17% higher risk. These benefits have been observed in a period as short as 4 years.[12,13] Furthermore, compared with no coffee consumption, 6 cups of coffee per day is associated with a 33% lower risk for T2DM. The association remained strong regardless of whether the coffee is caffeinated.[14]

In summary: Most studies of large databases from diverse countries point to the same conclusions and suggest that as part as a healthy diet and lifestyle, drinking black coffee (with little or no milk or sugar) regularly can contribute to diabetes prevention. However, there are no official recommendations.
